The General Society of Mayflower Descendants — commonly called the Mayflower Society — is a hereditary organization of individuals who have documented their descent from one or more of the 102 passengers who arrived on the Mayflower in 1620 at what is now Plymouth, Massachusetts. The Society was founded at Plymouth in 1897.

Today, it is estimated that up to tens of millions of Americans have at least one ancestor who was among this group of early settlers.[1] The following are the names of 31 adult Mayflower passengers currently known to have descendants.

In 1941 the Society purchased the Edward Winslow House in Plymouth, Massachusetts. The mansion home was originally built in 1754 by the great-grandson of Edward Winslow, third Governor of Plymouth Colony. The Society operates the home as the Mayflower House Museum, an 18th-century historic house museum with period decorations and furnishings. The offices and library of the General Society of Mayflower Descendants are located behind the mansion.
